HSI: omap_ssi_core: Fix error handling in ssi_init()

2023-01-18T10:30:30+00:00

[ Upstream commit 3ffa9f713c39a213a08d9ff13ab983a8aa5d8b5d ]

The ssi_init() returns the platform_driver_register() directly without
checking its return value, if platform_driver_register() failed, the
ssi_pdriver is not unregistered.
Fix by unregister ssi_pdriver when the last platform_driver_register()
failed.

HSI: omap_ssi_core: fix possible memory leak in ssi_probe()

2023-01-18T10:30:29+00:00

[ Upstream commit 1aff514e1d2bd47854dbbdf867970b9d463d4c57 ]

If ssi_add_controller() returns error, it should call hsi_put_controller()
to give up the reference that was set in hsi_alloc_controller(), so that
it can call hsi_controller_release() to free controller and ports that
allocated in hsi_alloc_controller().

[ Upstream commit f5181c35ed7ba0ceb6e42872aad1334d994b0175 ]

In error label 'out1' path in ssi_probe(), the pm_runtime_enable()
has not been called yet, so pm_runtime_disable() is not needed.

HSI: omap_ssi: Fix refcount leak in ssi_probe

[ Upstream commit 9a2ea132df860177b33c9fd421b26c4e9a0a9396 ]

When returning or breaking early from a
for_each_available_child_of_node() loop, we need to explicitly call
of_node_put() on the child node to possibly release the node.

[ Upstream commit a1ee1c08fcd5af03187dcd41dcab12fd5b379555 ]

cl is freed on error of calling device_register, but this
object is return later, which will cause uaf issue. Fix it
by return NULL on error.

HSI: core: fix resource leaks in hsi_add_client_from_dt()

[ Upstream commit 5c08b0f75575648032f309a6f58294453423ed93 ]

If some of the allocations fail between the dev_set_name() and the
device_register() then the name will not be freed.  Fix this by
moving dev_set_name() directly in front of the call to device_register().

failes to allocate an ID. Just return to fix it.

headers: separate linux/mod_devicetable.h from linux/platform_device.h

At over 4000 #includes,  is the 9th most
#included header file in the Linux kernel.  It does not need
, so drop that header and explicitly add
 to source files that need it.

   4146 #include 

After this patch, there are 225 files that use ,
for a reduction of around 3900 times that 
does not have to be read & parsed.

    225 #include 

This patch was build-tested on 20 different arch-es.

It also makes these drivers SubmitChecklist#1 compliant.

hsi: clients: Change return type to vm_fault_t

2018-04-17T14:05:26+00:00

Use new return type vm_fault_t for fault handler. For
now, this is just documenting that the function returns
a VM_FAULT value rather than an errno. Once all instances
are converted, vm_fault_t will become a distinct type.
